Wanted..Millers Falls Langdon Acme Mitre Box

I am trying to purchase an Acme Mitre Box. I want to use it occasionally but mostly keep it in my collection of old tools. In a perfect world I would like to find one that had been stored away and never used…but that is not likely. I do want to find one with all the pieces still in place. Does anyone have one or know where i might find one?
